Posting Duration: This posting will be open for application submissions for a minimum of seven (7) calendar days, including the ‘posting date’. Sandia reserves the right to extend the posting date at any time. COVID-19 Vaccination Mandate: Sandia demonstrates its commitment to public safety in the national interest by requiring that all new hires be fully vaccinated or have an approved medical or religious accommodation before commencing employment. The requirement also applies to those who are telecommuting and working virtually. Any concerns about the ability to meet this requirement should be directed to HR Solutions at (505) 284-4700. What Your Job Will Be Like: We seek a hardworking postdoctoral appointee for research in the area of modeling device physics and defect physics within a multiscale, atoms-to-devices effort to understand radiation effects in semiconductor materials and microelectronics. The interdisciplinary effort integrates first principles calculations of atomic defects, defect-aware device simulations, and experimental characterization of defects in irradiated semiconductors. This position will focus on fundamental research in device theory for development and implementation of defect-based damage models for reactive transport device simulations (in Sandia's REOS research device software) based on first-principles-derived and experiment-obtained defect data, validated by experimental device data. This will involve developing reaction mechanisms governing materials response to irradiation. This position will require close collaboration with diverse colleagues (DFT computation, device theory, and experiment) from multiple organizations, and the expectation is that the appointee will engage the with the wider expertise at the Laboratories and with our external partners involved in radiation effects research and also electrical breakdown applications. A prime example of purposeful science, this fundamental research will be published in peer-reviewed literature and be presented at appropriate conferences. Join our team of scientists and engineers in doing phenomenal science with impact on real engineering problems. Qualifications We Require: + Have, or soon to acquire, a PhD in Physics, Electrical Engineering, Chemical Engineering, Materials Science, or related science or engineering field pertinent to device and defect physics + Experience in modeling of electronic/ optical materials and/or devices + Record of research and analytic thinking abilities as proven by publications in peer-reviewed journals and presentations at scientific conferences + Ability to acquire and maintain a DOE security clearance Qualifications We Desire: + Experience in code development for scientific applications + Experience in radiation effects research for electronic materials, especially III-V semiconductors + Proficiency in programming (esp. FORTRAN and Python) and facility applying software quality practices and tools + Experience with using and developing device modeling software, either custom (e.g. REOS or CHARON) or commercial (e.g. SILVACO Atlas or SYNOPSIS Sentaurus) + Experience with electronic structure modeling for atomic-scale defects in semiconductors, e.g. using VASP, Quantum Espresso, SeqQuest, etc + A dedication to encouraging an inclusive culture, as proven in your application materials + Interest in impacting applications and customers in support of DOE missions About Our Team: The interdisciplinary project integrates, theory, and experiment from multiple organizations across the Laboratories to understand radiation effects in electronic materials. These organizations combine expertise across multiple fields to tackle science and engineering problems in support of DOE missions. Our team brings together leading authorities in density functional theory defect calculations, device theory and modeling, and radiation effects experiments, and access to frontier computing capabilities and premier experimental facilities such as Sandia's Ion Beam Laboratory. The successful candidate will be a member of the Computational Multiscale Department within the Center for Computing Research, which performs wide-ranging research and development in physics-based materials modeling and high-performance computing ranging from electronic structure (the SeqQuest code) and molecular dynamics (LAMMPS) through continuum mechanics. Our team is committed to a nurturing environment compatible with a broad group of people and perspectives in accordance with the changing makeup of the workforce. In support of this vision, our center actively recruits applicants from diverse groups of backgrounds and fosters an inclusive community. Join us and work towards your goals while making a difference!

Security Clearance:

Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment need to be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted. Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment. EEO: All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status and any other protected class under state or federal law. Position Information: This postdoctoral position is a temporary position for up to one year, which may be renewed at Sandia's discretion up to five additional years. The PhD must have been conferred within five years prior to employment. Individuals in postdoctoral positions may bid on regular Sandia positions as internal candidates, and in some cases may be converted to regular career positions during their term if warranted by ongoing operational needs, continuing availability of funds, and satisfactory job performance.
